RECOMMENDED PRACTICE: All controls should be selected consider-ing the media and ambient operatingconditions. Improper application can be detrimental to the switch, cause failureand possibly personal injury or property damage. Applications include: pumps, compres-sors, washers, filters, degreasers,evaporators, recovery systems, foodprocessing, ground support equip-ment, reverse osmosis systems, heatexchangers, hydraulic systems, lubrica-tion systems, marine equipment, textile machinery, heating and air conditioning equipment.

Hermetically Sealed Switch A switch element whose con-tacts are completely sealed from the environment to provideadditional safety and reliability. Contact arc cannot cause anexplosion, and atmospheric corrosive elements cannot affectthe contacts. Manual Reset Switch ֖ Pressure or Temp-erature switch inwhich contacts remain actuated even after the actuating vari-able returns to normal. On Ashcroft manual reset switches, abutton must be pushed to reset the contacts. > National Electrical Manufacturers Association (NEMA) Thisgroup has defined several categories of enclosures, usuallyreferred to...

Appicable Switch Series DifferentialTemp- ATEX is a European designation thatdeals with standards for equipment andprotective systems intended for use in potentially explosive atmospheres. Thisapproval is required for switches intendedfor use in hazardous locations, especially important to OEMs who export to Europeand contractors specifying or purchasingproducts for European applications. XCN option adds special features toAshcroft 700-Series switch enclosuresthat meet the requirements for the highestlevels of security and danger, such as:?Special locking device requiring an Allenwrench to remove...

XG9 FIRE-SAFE WELDED ACTUATOR > The Ashcroft pressure switch actuator isdesigned to satisfy most medium range pressure switch applications. It has only two wetted parts; pressure port and diaphragm. No O-rings are requiredbecause all joints are welded. The Ashcroft medium pressure gas andoil limit control switch is designed for use with air, LP gas, natural gas, #1 and #2 fuel oil and #6 oil preheated to 240ְF. This limit control is an adjustable pressure operated switch with a sec- ondary chamber to prevent fuel fromentering the switch enclosure in theunlikely event that the diaphragm devel-...

STEAM SERVICE In order to prevent live steam from cominginto contact with the switch actuator, a siphon filled with water should be installed between the switch and the process line. We recommend the optional stainless steelwelded process connection and diaphragmeven though viton is rated for use with steam. Expe- rience hasshown thatin many steam appli-cations, the300F high temperaturelimit of Vitonis exceeded by steam under pres-sure.In some boiler applications, a special U.L.listing, ГMBPR, which requires unique fea-tures, is needed. Dresser offers these fea- tures with option XG8. Refer also...
